[texts]18. Eng Microstrip Satyandra Singh Lodhi - Satyandra Singh Lodhi & P. K. Singhal
This paper propose a novel design of microstrip Yagi-Uda antenna at 2.45 GHz for ISM (industrial, scientific and medical) band application. The proposed antenna consists of pair of reflector, a driven element and three directors.                   The antenna had achieved directivity of 5.95 dBi, gain of 4.496 dB, return loss of -41.5 dB and high efficiency. It has been fabricated on the FR-4 substrate with dielectric constant of 4.4, loss tangent of 0.02 and substrate height 1...

R&D Report 1974-32 : UHF amplifiers: improvement of linearity by pre-correction A.G. Lyner, P. Shelswell The basic principle of pre-correction for improving amplifier linearity is discussed with some theory and the idea of pre-correction using an error signal injection system is introduced. A description is given of a practical form of pre-corrector which was used successfully to double the output power of a transistor amplifier for a UHF television combined sound and vision signal.
